But C999, "shagging" is exactly what you are doing. "Love" doesn't seem to come into it for you. Unless you count the eventual love you will have for the child, I suppose. This is one thing I've really struggled with when reading your posts and I feel like it somehow cheapens what I have with my OH
And Mushi is right, the moment you have unprotected sex after an STI test, that test becomes invalid. It only takes one infected partner to blow the whole thing out of the water.
As so many people have now said (both on this thread and the other one about ONSs), why not consider a donor? That way you're at least getting sperm which is safe for you and the unborn child and is coming from a man who's made a conscious decision to help someone become a mum.
Finally... you keep mentioning your age, but you're 37 not 47! There is still time to meet someone with whom you could "make love" and bring up a child. Have you looked into internet dating... some people on those sites make it very clear that they are hoping to have a family and it can all move quite quickly.
Sorry for the long post - been bottling some of that up. I promise I'm not trying to flame or attack you, and I apologise if it comes across like that, but as we're all revealing such personal stuff on this forum I felt it would be disingenuous to just continue saying nothing.
